COUCH-SPRING.

SPECIFICATION forming part of Letters Patent N0. l754,835, dated March 15, 1904. Application led December 1Q, 1902. Serial Nol34,642. (No inodel.)

To all whom, t may concern;

Be it known that I, ERNEST A. ANDERSON, a citizen of the United States, and a resident of Jamestown, in the county of Chautauqua and .State of New York, have invented a new and useful Couch-Spring, of which the following, taken in connection with the accompanying drawings, is a full,clear, and exact description.

My invention relates to metallic spring-bottoms for lounges and like articles of furniture in which the cone springs are supported upon cross-wires; and the objects of my improvement are, first, to provide a wireslat for supporting the springs and staying the frame, and, second, to provide a wire connection for the tops of the springs, whereby each spring has a certain freedom of action, yet is supported by and connected on all sides with the adjacent springs. A

In the drawings, Figure 1 is a plan view of part of a couch-fraine having my spring-bottom thereon, the two vertical rows to the left showing the complete springbottom, the three middle rows showing the cone springs and my connecting-wire for the tops of the same, and on the right is a .plan view of my wire slat without any springs thereon. Fig. 2 is a detail showing'the usual manner of attaching my connecting-Wire to the springs. Fig. 3 is a plan view of wire slat attached to the frame having the lower portion of the cone springs secured thereon and a portion of the deadening-'strip woven therein. Fig. 4 is a side elevation of the parts shown in Fig. ,3 with the side rails in section and 'showing the usual method of attaching my wire slat'tothe,

rails. Fig. 5 is a sectional view at line X X in Fig. 3.

Similar numerals refer to similar parts in the several views. Y l

The numeral 10 is the frame. The ends 11 of the large sustaining ,cross-wires 12 of my wire slat are usually bent at right angles and inserted into the upper edge of the frame 10, as shown in Fig. 4. The wires 12 are then carried down toward the lower edge of the frame and extended out at right angles from the frame-piece 10 and across to the opposite frame-piece, where they are fastened in like The ends of wire 15 are secured to the framepieces at 17. This stretches the wire 15 -irmly into position upon the wires 12 and holds the springs. The bottom wires 18 of springs' 14 are turned under the stif interlacing wires 15, as at 19, on each side of the spring, so that the cone springs are held firmly in position upon supporting cross-wires. It is recognized that in all metallic spring-bottoms the clicking of the metal parts as the.

springs are compressed is objectionable. I therefore insert a deadening-strip 20, of felt or other suitable material, through and over the wires 15. It will now be seen that the springs as 4they compress-will strike strip 20, avoiding all sound.

The tops of the cone springs 14 are connected by wires 21, which run diagonally between the springs in each direction, and` I make a bend or return curve opposite thev point of contact with each spring and unite the central portion of the bend to the spring bya simple wire loop 23, as clearly shown in Fig. 2. Bend 22 in the connecting-wire vallows spring 14 to be depressed for some distance without drawing upon the connecting-wires, since the bends v22 will turn downward from their normal horizontal position. This gives acertain degree offreedom of action to sp'ring`14, while the spring is held on all sides and from all directions and a complete wire top is made for supportingthe mattress. The ends 24 of the connecting-wires 21 are given a return-bend, as shown, and the bend connected by wire loop 23 in order that the outer row of springs may have the same freedom of actionas the central springs. A heavy edge wire 25 is secured to this outer row of springs by wire loops 23 to give a stiff supporting edge to my spring-bottom.

It is apparent that the bend 22 in connect- IOO ing-wire 21 prevents the loop 23 from slipping along the wire, and thus displacing the spring; also, that the draw of the connecting-wires 21 is in all directions. It is obvious that my wire slat can be used for a bed-slat and that it has great supporting strength. Being attached to the frame-pieces on each side and made of large-sized wire, the slats do not need lengthwise attachment to each other. The stiliLl interlacing wire 15 is not usually wound around both the wires 12, but after surrounding one is passed in between the two wires l2 and then around the opposite wire, thus forming an interlace which when stamped upward into place by a suitable die surrounds the wires 12, as shown at 16 in Fig. 5, and firmly holds the Slat in ,form and makes the upper, side Hat to support the springs. It is also apparent that my bed-slats may be made complete, as shown, and then attached to the frame, which is usually the simplest and cheapest manner of manufacture. The hooked ends of the side wires may embrace the side rails without being inserted in the upper edge, or any other method of attachment may be employed for my wire slat without departing from the purpose of my invention. In like manner the interlacing wire may be fastened to the side wires at each end and serve a good purpose, but not as good, since it would notstretch the interlacing wire and make the slat as stili and strong.

I claim as new- 1. In a couch having a suitable frame, wire slats composed of heavy cross-wires, the ends of said wires having attachment to said frame,

a stiff wire interlaced between said cross-wires, and each end of said interlaced wire attached to the frame.

2. In a couch-bottom, wire slats composed of heavy wires crosswise of the frame and having their ends attached thereto, a stiftl wire continuously interlaced between said side wires and attached to said frame, cone springs on said slats having their bottom coils inter- 4C. In a couch having a suitable frame, a`

couch-bottom composed of wire slats having,

heavy cross-wires with ends attached to said frame, wire interlaced between said crosswires, cone springs on said slats interlocked with said interlacig wire, connecting-wires for the tops of said springs having return curves opposite to and outside of each spring and connected loosely thereto.

In testimony whereofI have signed my name to this speciiication in the presence of two subscribing witnesses.
